Ahead of the advent of heavy machinery the raw ore was split up using hammers wielded by hand, a procedure called “spalling”. In a short time, mechanical means put together to achieve this. For example, stamp mills were chosen for Samarkand as early as 973. These were also being used in medieval Persia. By the 11th century, stamp mills were in widespread use through the entire medieval Islamic world, from Islamic Spain and North Africa in the western world to Central Asia inside the east. A later example was the Cornish stamps, that includes a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling about the ore under gravity.
The easiest method of separating ore from gangue contains the selecting the individual crystals of each and every. This can be a very tedious process, particularly when the person particles are small. Another comparatively simple method depends on the various minerals having different densities, causing them to collect in different places: metallic minerals (being heavier) will give up of suspension quicker than lighter ones, that is carried further by way of a stream of water. The process of panning and sifting for gold uses both these methods. Various devices known as ‘buddles’ were chosen to consider good thing about this property.
Dryer can be used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be utilized for drying many kinds of materials along with convenient and reliable operation. As the professional manufacturer of complete sets of mining machinery, such as clinker rotary kiln, impact stone breaker , HXJQ is always doing the best in products and service.
This machine is principally found in ore selecting, building materials, metallurgy and chemicals to dry the types of materials with certain moisture and size. The rotary drier includes a strong adaptability which could dry many different types of materials having a simple operation method and security trait, so it is traditionally used.
Ball mill is surely an efficient tool for grinding many materials into fine powder. The Ball mill is utilized to grind many kinds of mine as well as other materials, or select the mine. It is traditionally used in building material, chemical industry, etc. There are 2 means of grinding: the dry process as well as the wet process. It may be split into tabular type and flowing type in accordance with various forms of discharging material.
Magnetic Separator can separate the raw materials with various magnetic rigidities. The device works beneath the magnetic force and machine force. Magnetic Separators are designed to recover ferromagnetic materials. The separators are available in designs and sizes to provide solutions for many applications. The center of every separator will be the magnetic system with its unique design, with a proven record of high efficiency. The Magnetic Separators can be found in cyclic design with process vessel diameters from 220 mm to three,050 mm.
